Global food security demands sustainable alternatives to the conventional feed ingredient wheat. Nutrient-dense diploid potatoes (HQP) represent candidates due to their enriched phytochemical profiles, including high levels of vitamin C and lutein. However, their dietary utilization is constrained by endogenous anti-nutritional factors (ANFs), primarily solanine and trypsin inhibitors. Using a zebrafish model, we demonstrate that these ANFs trigger intestinal dysbiosis and an oxidative-inflammatory response. Mechanistically, this adverse gut environment suppresses the mTOR pathway, as evidenced by reduced phosphorylation of S6K1 and 4E-BP1, ultimately leading to growth depression. To address this toxicological barrier, we integrated genetic selection (diploid HQP) with thermal processing (steam-cooking). Quantitative analysis revealed that while thermal processing effectively reduced ANF concentrations to physiologically safe levels, the HQP matrix retained significantly higher residual concentrations of vitamin C, lutein, and zeaxanthin compared to conventional tetraploid (C88) and wheat-based diets. Mechanistically, protein-level evidence confirmed that this processed HQP formulation promoted the total NRF2 and suppressed NF-κB P65 accumulation. This metabolic shift attenuated inflammation, reactivated mTOR signaling, and subsequently enhanced growth performance and digestive capacity. Our findings establish a mechanistic framework demonstrating how integrated genomic design and processing strategies facilitate the functional utilization of high-phytochemical crops in sustainable food systems.

Abstract Indoor air quality can be improved by coatings that adsorb harmful volatile organic compounds (VOCs). In the present work, bio-based and VOC-adsorbing wood coatings were fabricated from polyphenols extracted from spruce bark, biochar produced from mixtures of spruce and pine bark, and a polyamine crosslinker. The bark-based biochar was doped with a catalyst (MnO 2 ) to enable continuous elimination of the adsorbed VOCs so that the coatings would not become saturated. The coatings formed a homogenous and smooth layer that covered the whole surface of the wood and showed excellent adhesion to the substrate, while their VOC removal efficiency was dependent on the pollutant type and the coating weight. The best performance was achieved toward formaldehyde, followed by chloroform and methyl ethyl ketone. Thick coatings (200–220 g/m 2 ) reached a formaldehyde removal of 62%, with the coating base and the biochar contributing nearly equally to the VOC removal. Overall, the bark-based coatings showed good potential for improving indoor air quality, but the surface wettability of the coated spruce wood was high. Despite the presence of biochar and nitrogen-containing aromatic compounds, the coatings did not appear to improve the reaction to fire of the wood.

Før-og-nå-fotopar viser endringer eller kontinuitet i landskap, natur og samfunn over tid. NIBIO har mange fotopar fritt tilgjengelig for ikke-kommersiell bruk, for eksempel i skoleoppgaver.
Sammendrag
Før-og-nå-fotopar kan være et godt virkemiddel for å vise endringer i våre hverdagslandskap, og de kan være grunnlag for ettertanke: • Hvorfor har det blitt slik? • Var det slik man ønsket eller tenkte at det skulle bli? • Ønsker eller trenger vi mer av slike endringer, her eller på andre steder? • Eller ønsker vi å stoppe eller reversere utviklingen? Når du har et foto fra et sted du kjenner til, kan det være lærerikt å prøve å ta bildet «på nytt».

Før-og-nå-fotopar kan være et godt virkemiddel for å vise endringer i våre hverdagslandskap eller omgivelser. Når du kjenner til eller mistenker kommende endringer som du ønsker å vise frem, kan det være lurt å ta foto som utgangspunkt.
